TYPE-WFHTER.

- United Stat-es Navy, and a resident of Ala:

etes a platen 1,3.

moda, Alameda county, State of California,

have invented a new and Improved 'Iypell'iitei', of which the following is a .ull, clear, and exact description,

ly invention relates to typc-writers, and

more particularly to mechanism for returning the carriage to its initial position and forv advancingr the platen. Its principal ohvjects are to provide means for effecting the reversal and feed, either automatically or manually, with minimum effort on the part of the operator, and in either case to effect this speedily and with little shock upon the niachine.

It consists in the various features and coinbinntions hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forining a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a top plan view of a type-writer to which one embodiment of my invention is a iplied. Fig. 2 is an enlarged partial front. cievation thereof, and Fig. 3 shows diagraminatically the magnet with the circuits and cireuit-closcrs in connection with a portion of the type-writer.

The numeral l() designates the frame of one forni of ty e-writer, in eonnection'with which I have c losen to illustrate my invention. This type-writer is provided with a keyboard Il and acarriajze 12, in which oper- Associaed with the cnr- Specification of Lettera, Patent.

l of the drawings as a series of cells 21, com- E priced in a 'circuit 2,2.V These may be either primary or secondary elements, or the magnet may be connected with a lighting or lowcr circuit, either alternating or direct. q Near the magnet, preferably upon the upper iside thereof, are mounted brackets or supi porting-bars 23 23, formed of non-magnetic material and carrying, swinging upon a rod 23 at one extremity an armature 24.l From the opposite side of this armature projects an arm 25, lpreferably o f brass or other non magnetic material, havi at its outer end a depending segmental ralcl 2G, meshing with a pinion 27, fast upon afshaft 28. This shaft is journaled in the outer ends of the brackets 23 and has fixed to it a roll 29, to the periphery of which issccured a flexible member or banr'l 30, which may be conveniently formed of thin metal. The inner @d of this brindis fastened to a lever 31, here shown as fulcrumed upon the' bracketflQ beneath the mag'net and connected at its upper end to the spacing-lever by a linkf?.

'Ihe relation of the throw of the armature and its rack to the number of teeth uponthe pinion and the diameter of the roll is such that upon the energizing of the magnet to draw down its armature the winding of the hand about theroll will move the carriage from its extreme left-hand to its initial position with a constantly-exerted for'ce and at upon the spacing-lever to rotate the platen through thecoac'ting dog and advance the work to the next line. 'Ihe completion of the normally open magnet-circuit 22 to effect this result may be accomplished by-a conriagc is a line-spacing lever 14, carrying the l tact device or circuit-closer consisting of spacing-dog 15jor coaction with the platen. f'spring members 33 and 34, suitably mounted Mounted' upon the carriage are right and!! upon an insulating-base 34, adjacent to the left hand inargin-stops IG and -17, havingi` keyboard and connected with `the magnetslop projections 1G and 17a, respectively]i circuit by leads 35. Pivotally supported upon the frame isa mos@ be operated by a bell-crank lever 36, fu able member 18, which serves as a stop and erurned upon the frame'of the type-Writer locking-lever. and coi erating at one end with a head 37,

Fixed to the base of the machine, prefercarried )y the upper cont act member 33, ably at the right thereof, is a bracket l19, cari while its opposite end is articulated to a key vice, which `is here shown as 'a double-pulci machine.- `This: manually-1 ernted circuitrying at its outer end an electromagnetic de i 38, adjacent to -the bank# keys of the electromagnet 2U. The winding of this mag-l l closer enables the carriage to e reversed and net will depend upon the source of the 'elee-A l'thc' platen rotated from 'any point of its triciil energy which is supplied to it, this betravel. han the last character of thelast ing in the present instance indicated inFigj3 l word of a line falls upon thagraduation next the same time will throw sufficient tension 'Ibis circuit-closer map' IOC tio

to the right-hand margin-stop, this reversal and feed may be accomplished automatically, and for this purpose a circuit-closer is provided consisting of a fixed contact member ,Y 3S), secured to the frame of the machine, with which coacts a movable contact inember 40, carried by a lever 4l, conveniently fulcrunied upon a pin 42, rising from the frame. 'lhese two members are connected with the magnet-circuit through leads 43, joining this circuit-closer in parallel with the manually -operated device. The contact member 40 is situated adjacent to the locking-lever 18 and in its path. From the arm of the lever 41 projects a pin 43", and upon the locking-lever is a collar 43h, from which extends a spring-arm 44 at the other side of the pin 43a from the lever and adapted to contact therewith. 'lhe lever 18 moves in a recess in the frame of the machine and when in normal position bears against the wall 18 at the right-hand side of the recess, which thus forms a stop for the lever. A coilspring 43. is connected with the lever 18, the spring yielding to permit tli lever to be moved toward the left by the carriage and returning the lever to its normal position w hen the carriage starts on its return movement to the iight. As the carriage approaches the termination of its movement toward the left 'the stop projection 16 contacts with the lever 18 and moves it before it against the tension ol' the spring 43". As the end of the lever 41 is resting against this locking-lever the former lever is swung upon its fulcrum, and when the carriage has reached the end of its travel the contact members 39 and 40 will come into conction. rlhis closes the circuit( it is ready for coaction with reverse travel oi' inc carriage the contact members 39 and 40 will be separated and the lever will assume a position indicatedin dotted lines in Fig. 3 of the drawings, at which the locking-lever upon the completion of the line.

It'will be understood that when the carriage moves tothe left and the lever 41 is move the member 40 into engagement with the fixed contact member 39 the lever 41 remains in this position until the spring-arm 44 is moved against the in 43 by the stop projection 17. Whent ie carriage starts on its and the latter is returned to its normal position by the tension ofthe spring 43". The lever 18 is not moved sufficiently to cause the springarm 44 to bear on the in 43,;and consequently the.springarm as no tendency to the said spring-arm projection 17..

n van be Seen that by ihempioymeni'bf t e end of theline and that the relieved of the necessity'of removin abled to operate with much greaterjfacility and at vastly increased speed. Moreover the shock and consequent deterioration of through the magnet, attracting the armature, which moves directly toward the faces ofthe magnet-poles'in the general direction of the lines of force and through the connecting means drawing back the carria 'e to its extreme position at the right andi simultaneously swinging the spacing-lever to advance the platen. As the attraction of the magnet for -its armature, and consequently the ve-V locitv imparted thereto and -to the carriage, will increase as the armature approaches the poles, itI is necessary that some provisionl be made toiheck the increasing momentum to 'avoid severe concussion hen the carriage reaches a stop at. the right of the machine.

does'occur being sprin 2 absorbed bythe vield of the invention I have shown it as'applied to a specific type oflmachin, it will beevident that it may be adapted toany other form, and it is therefore .to be understood that changes directed to this end are within the scope of my `invention.

YHaving thus described my invention, I claim as new Patent- .t

1. The coiibination with a ,type-writer drame, a carriage movable thereon, and a. bracket securedto the frame, of an electro- 'lhis is cfl'ected by the contact of the. stop projection 1T with the spring 44, which furi nishes a cushion. This spring will be allowed sufficient yield so that even if the inarginsto is adjusted for the first `graduation there g will)still be a sufficient depression before the stop ordinarily set in the carriage-track.isI reached to furnish the proper yield. As the springr is moved to the right by the stop prot jection 17l it contacts with the pin 43" and I moves it before'it. so that at the end of the l pinion meshing with the rack segmental rack carried by the armature, a;
